LAND-'HLLEWn Specification of Letters Patent.

Patented Aug. 22, 1905.

Application filed September l5, 1904. Serial No. 224,537.

To all whom t may con/cern:

Be it known that we, HARRY E. You'rz and HARVEY Z. You'rz, citizens of the United States, residing at Mountville, in the county of Lancaster and State of l.)ennsylvania, have invented certainvnew and Vuseful Improvements in Land-Rollers; and we do hereby declare the following to be a full, clear, and exact description of the invention, such aswill enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in a land-roller of that class which is set forth in Patent No. 524,536, dated August la, 1894.1.,

. granted to .l ames F. Youtz, and it may be considered as extending the scope of said invention; but our present invention relates more particularly to the construction of the roller-head as well as to the formation of its hub and the mounting of the sleeve or thimble therein.

The object of the invention is to so construct the roller-head and the hub that the latter may be securely mounted at the center of the former, preventing' all shearing' therebetween, and in which provision is made to conveniently and expeditiously remove wornout parts therefrom and replace them with new ones.

The elements of theinvention will severally and at large appear in the following description, and they will be separately and combinedly pointed out or set forth in the appended claims.

The purposes of the invention are attained by the mechanism, devices, and means illustrated in the accompanying drawings, with similar reference characters to designate like parts throughout the several views, in which Figure l is an outside elevation of the lefthand. end roller-head embodying the elements of the invention; Fig. 2, an inside elevation of the same head; Fig. 3, a longitudinal central vertical section of the left-hand portion of the roller, showing the end-supporting hanger with a portion of the roller-frame in place; Fig. t, an enlarged section of the central portion of Fig. l, the section being taken on the line fr .fe and vertically placed; Fig. 5, a similar section to Fig. 4e, but taken on the line y y/ and similarly placed; Fig. 5, a completed and direct elevation of the lower end of the corrugated portion of Fig. 5; Fig. 6, a direct' and inverted plan of the hub or bushing plate as it appears when detached from Fig. l1. and enlarged; Fig. 7, a direct sectional elevation of the hub-lmshing, with the retaining-key, the securing-bolt, and the sleeve or thimble in place; Fig. 8, a direct and enlarged plan of the central portion of the head, showing the bushing-aperture with the keyseat therein and the angular bolt-oriiices in the sides thereof; and F ig. '9, an enlarged side elevation and a direct plan of the securingbolt with the nuts thereon as they appear when detached from Fig. et.

ln the drawings, A designates the left-hand end roller-head, being a circular disk of the required dimensions, preferably punched from approved sheet-steel, the disk having` an outwardly-turned peripheral rim or fiange a, to the outer surface of which is secured the lefthand end of the cylindrical roller-drum A', as by bolts a passed therethrough with nuts a2 on their threadedl ends. In the body of the disk, on the outer surface thereof, are raised radial corrugations a3 in the semblance of spokes, imparting strength thereto. At the center of the disk is a circular aperture ai, to be engaged by the cylindrical part of the hubplate or bushing yet to be described. In the peripheral edge of said aperture is an angular recess or notch a for the seating of a key attached to said cylindrical part, preventing' it from rotating or turning, while on the diametrical line at the required distances from the center thereof, through the body of the disk, are formed angular orifices a a, through which bolts yet to be described serve to se-l cure said bushing or hub plate in place.

Applied to the outer surface of the disk, at the center thereof, is a hub-plate or bushing l, with a tubular portion engaging through. said aperture ai, said tubular portion having an axial bore L for seating the sleeve or thiinble, to be hereinafter mentioned. At the required point around the convex surface of said tubular portion, integral therewith, is a circular plate or ring-flange 'of of the required dimensions to engage `against the adjacent su rface the` disk and having in the peripheral ledge thereof under-surface recesses 53, to be engaged by the inner ends of the disk-corrugations a when it is placed in position thereon, preventing all shearing motion or rotation, while in the outer surface of said tubular portion at the required point and longitud inally disposed is seated a key to engage in the angular notch rf of the disk, aiding in preventing said shearing rotation. At diametrically opposite points of the ring-flange b2, between the adjacent pairs of the edge recesses b3 and projecting outwardly from the tubular portion b, are formed upwardly-thickened portions 5*, having in their under surfaces nuthousing recesses ZJ, in which nuts, to be hereinafter mentioned, serve to secure the bushing-securing bolts to the body of the disk, while at the center of recesses through the top walls of said thickened portions are formed orifices bs for the passage therethrough of the threaded portions of said bolts.

For the purpose ofsecuring the bushing to the disk, bolts C C are applied thereto, and to this end said bolts have fiat-surfaced heads c engaging against the inside surface of the disk, and from the fiat surfaces of said heads project angular portions c', fitting into and engaging through the angular orifices a of the disk, and the bolts from said angular portions forward are provided with screw-threads 02, while nuts C C', screwed home thereon, serve to securely affix said bolts in place, with the recesses 65 housing said nuts when the bushing-plate B is placed in position on the disk or roller-head and the forward ends of the screw-threaded portions of the bolts passed through the orifices b of the thickened flange portions bwith nuts C2 C2 screwed home thereon, serve to securely affix said bushing-plate to the roller-head, and from which it may be readily removed by simply unscrewing and taking off the nuts C2.

Vithin the axial bore b of the tubular portion b of the hub or bushing plate B is seated a sleeve or thimble D, having at its forward end a surrounding ring-flange Z of the re- 'quired dimensions to engage against the outerend edge of said tubular portion, said sleeve having lengthwise through its body in the axis thereof an angular aperture or opening d', through which is passed a closely-fitting axle-bar or roller-shaft D,extending throughout the length of the roller and having outer ends, like its left-head end (Z2, closely engaging the angular opening' (Z3, formed in the lower end bars of the hanger D2, with its upper end secured to the under surface of the base-plate of the roller-frame D3, as by bolts clpassed therethrough, with nuts (Z5 screwed home on their threaded ends, while a nut D* on the threaded end CZ of the shaft and firmly screwed home against the hanger serves to securely bind the hanger and sleeve together, holding the sleeve rigidly in position, the right-hand end of the shaft having been similarly treated but oppositely disposed.

It will here be remarked that with the construction of the hub or bushing plate B with the mounting thereof on and securing it to the roller-head A by means of bolts C, all as hereinbefore described, determine or conclude the elements of the present invention,

for the sleeve D, with the shaft D', the hanger D2, and the mounting thereof onto the rollerframe D3, being all as described or set forth in the patent to J ames F. Youtz, hereinbefore mentioned, are not claimed as elements in this, but are used only to complete the construction.

rIhe invention having thus been ascertained and described and the manner in which its functions are performed fully shown and set forth, what is considered new, and desired to be secured by Letters Patent, is-
